Unfortunately i have upgraded onto 2 live sites, everything seemed ok, but unfortunately i did not properly test before compounding my mistake by upgrading on another site.
I have disabled pluggins, flushed cache, reselected permalinks to no avail.
Uses thesis 1.8.5 static pages are fine, and click through without problem. blog posts exist if i directly paste the url in the browser bar without problem. however if any category page links in my nav menu are 404’d
Uses a themepress theme, which is quite heavy on category links. again the same issue. static pages re fine, category links are 404’d
I have rolled back to previous backups ( 3.4.0) which seems to be ok, and ad reluctant to upgrade again to 3.4.1 until a fix / root cause determined.
Does anyone have any suggestions? I’ve rolled back one site, would prefer to fix the issue on the other.
